HYDROCARBON-BURNER.

E5PECIPICATION forming part. of Letters Patent No. 351,954, dated November 2, 1886.

I Application filed September 19, 1885. Serial No. 177,536. (No model.)

. Be it known that I, WILLIAM BARRAOLOUGH, of Balmain, near Sydney, New South ales, have invented a new and Improved Hydrocarbon-Burner, of which the following is a full, clear, and exact description.

My invention relatesto the construction of a new and improved apparatus for generating and burning hydrocarbon vapor without the aid of a wick; and the invention consists of certain novel constructions and arrangements to be hereinafter explained, and specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part of this specification, in

which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a vertical sectional view of the apparatus, and Fig. 2 is a view of the heatingtubes.

A represents the supply-tank, within which there is secured adownwardly-projecting tube, B, into which oil is fed through the aperture a. To the lower extremity of' the pipe B, I secure a'coupling-piece, G, in which there is a valve-seat, I), arranged so that the supply of oil passing through the coupling may be regulated by a plug-valve, c, which is operated by a valve-stem, D, that extends up through the pipe B and carries a manipulating bar or wheel,

E, above the tank A, the lower end of the stem D being threaded to engage with a threaded' socket formed in the coupling-piece O. A horizontal pipe, G, extends outward from the coupling 0 and carries an elbow-joint or coupling piece, H, on its projecting end. The downwardly-projecting arm of the elbow-joint H carries a vertical pipe or tube, I, called the packing-tube, which consists of metallic tubing, the size of which will vary according to the size of the lamp or the amount of flame required. For lamps of ordinary size, I construct the same of five-sixteenths of an inch diameter. This tube can be of any length. For lamps in ordinary use I make it three inches. I pack this tube withpieces of glass,

, asa poor heat-conducting substance, and being that which I have found the most suitable niaterial, the pieces of glass being about the size of millet se'ed, and a grooved screw, J- J, is

placed at each end of the tube to prevent the glass from falling out. These screws have two grooves oneach side to admit ofthe fluids passing through. On the lower end of the packing-tube, and in a vertical line with it, is attached a nipple, K, consisting of a cylindrical piece of brass about half an inch long, having a hole, 0,. through its axis, said hole being about the one-hundredth part of an inch in diameter, and on its lower end a thread, upon which is screwed what I term the mixingprovided the same proportion is observed between the length and the diameter. This tube for an ordinary lamp has one hole on each side I near the top, in each of which is 'fixed horizontally a metal pipe or tube about two inches long in an ordinary lamp, these tubes M M being thus so disposed that they will be directly over the flame when the lamp is burning. For a large-sized flame, I may fix two or more of these lateral tubes in the mixing-tube.

The lateral tubes just mentioned may be either straight or curved, as shown in Fig. 2, the curved being preferable, but the straight being more adapted to a small-sized flame. I make these lateral tubes of about one-quarter inch diameter; butl have not found the diameter thereof to make any material diflerence so long as a fair proportion to other portions of i the apparatus is observed. I call these lateral tubes the heaters.

The apparatus is completed'bya burner, 0, being fixed to the lower end of the mixingtube, the same consisting of a short cylindrical piece of brass about one-half of an inch in length and one-half of an inch in diameter, hollowed for three'quarters of its length to fix onto the mixing-tube, and six or eight lateral holes from which the flame issues.- I construct the said apparatus of any suitable inetal -rpreferably of brass.

Having described the construction of the said apparatus, I now proceed to explain how the same is used and my invention carried into The fount being filled with kerosene-oil, the tap is slightly loosened, to allow of a small portion of the oil to pass through the tubes into the burner, and thenlturned off. When the apparatus is so adjusted, a portion or excess of the oil will drop through the burner, leaving a small quantity in the burner and tubes. Light is applied to the burner, and the kerosene therein will at once ignite, and the flame, enveloping the mixing-tube and packing-tube, in about'one minute of time will heat to the requisite degree the mixing-tube, heaters, and packingtube, while induced currents of air will pass through the heating-tubes or heaters. The tap being again turned on, to allow the oil to pass through the packing-tube, a continuous rush of kerosene-vapor will take place through the small hole in the nipple. The air in passing through the heaters is raised to ahigh temperature and mixes with the kerosene-vapor in the mixing-tube, and the mixture of kerosene-vapor and air .rushes out through thelateral openings of the burner with a force which could not be accounted for by the altitude of the column of kerosene, and the same burns with a white smokeless flame.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the reservoir and the burner, of the intermediate pipes or tubes,

one being filled with glass and having screws inserted in its ends, said screws having grooves in their sides, substantially as and for the purpose set forth.

2. The combination, with the reservoir and thebnrner, of the intermediate pipes, one being filled with glass and having screws inserted into its ends, which screws are provided with grooves in their sides, and a nipple connecting with one end of the glass-filled pipe and having a reduced hole or passage through its one end, which connects with a second or mixing pipe of said intermediate pipes, substantially as and for the purpose specified.

3. The combination, with the burner and reservoir, of the intermediate pipes and the curved lateral tubes connected to the said intermediate pipes and arranged above said burner, "substantially as and for the purpose set forth.
